Milling is the process of machining using rotary cutters to remove material [1] by advancing a cutter into a workpiece. This may be done by varying directions [2] on one or several axes, cutter head speed, and pressure. [3] Milling covers a wide variety of different operations and machines, on scales from small individual parts to large, heavy ...
Indexing is an operation of dividing a periphery of a cylindrical workpiece into equal number of divisions by the help of index crank and index plate. A manual indexing head includes a hand crank. Rotating the hand crank in turn rotates the spindle and therefore the workpiece. The hand crank uses a worm gear drive to provide precise control of ...
This results in increased belt and bearing life as well as consistent accuracy with no external cooling fans required, increasing rigidity and vibration dampening properties. Bridgeport Machines, Inc., is a machine tool builder founded in 1938 in the United States of America. [1] It manufactures Milling machines and Lathes.
Cutting speed may be defined as the rate at the workpiece surface, irrespective of the machining operation used. A cutting speed for mild steel of 100 ft/min is the same whether it is the speed of the cutter passing over the workpiece, such as in a turning operation, or the speed of the cutter moving past a workpiece, such as in a milling operation.
Rotary table. A rotary table is a precision work positioning device used in metalworking. It enables the operator to drill or cut work at exact intervals around a fixed (usually horizontal or vertical) axis. Some rotary tables allow the use of index plates for indexing operations, and some can also be fitted with dividing plates that enable ...
Facing (machining) In machining, facing is the cutting of a flat surface perpendicular to some axis of the workpiece. This can be applied in two different areas: Facing on a milling machine (perpendicular to the axis of movement), which involves various milling operations, but primarily face milling. Facing on a lathe (perpendicular to the axis ...

Milling cutter. Milling cutters are cutting tools typically used in milling machines or machining centres to perform milling operations (and occasionally in other machine tools). They remove material by their movement within the machine (e.g., a ball nose mill) or directly from the cutter's shape (e.g., a form tool such as a hobbing cutter).
